To all whom tm/ty concern:

Beit known that I, CESARE LUZATTO, engineer, asubject of the Emperor of Austria- Hungary, residing at Milan, Italy, have in- 5 vented new and useful Improvements in Apparatus for the Manufactureof Cakes of` Food for Cattle and the Like, (for which'l have obtained a patent in Belgium, No. 118,383, bearing date November 16, 1895; in Great Britain, 1o No. 21,841, bearingdate November 16, 1895;

in France, No.l 251,713, bearing date November 14, 1895; in Italy,` Vol. LXXV, No. 380, bearing date March 25, 41895, and Vol.` LXXIX, No. 28, bearing date November 20, 1895; in Austria, Vol. XXXXV, No. 2,906, bearing date August 19, 1895, and Vol.

XXXXV, No. 4,674, bearing date December 6, 1895; in Hungary, No. 2,871, bearing date June 4, 1895, and No. 4,760, bearing date Dezo cember 6, 1895; in Switzerland, No. 11,566,

bearing date November 16, 1895, and in Germany, No. 88,370, bearing date November 17, 1895;) and I do hereby declare that 'the follow` ing is a full, clear,.and exact descriptionfof the invention,which`will enable others Skilled inthe art to which it appertains to make and' use the same.

This invention relates to the manufacture of food for cattle and the like, such food be- V :1 shows in elevation, partly in sectiona ma 3o ing made in the shape of cakes and composed chiefly of fibrous substances; and the object of this invention is to improve the apparatus to be employed in making cakes of this and similar kinds of food, the cakes being of a ..35 composition calculated to meet every-requirement for the successful feeding of cattle and the like and being capableof resisting for a longtime destructive atmospheric infiuences. The cakes produced in accordance With this 4o invention are free from the drawbacks attachin g to all cakes for a similar purpose that have been hitherto introduced into the market, their characteristic merits in this respect being great density and a remarkable power for resisting putrefaction and the fact that they may be conveyed from place to place Without breaking or crumbling, all of which advantages are mainly the outcome of the novel method of manufacturewhich my im- `steam being brought into as close contact as I possible with all parts of the mixture, so as to render it sufciently mold able for being in the l most simple and direct manner made into the `shape of cakes by the compressing or molding operation hereinafter described. 1t is desirable that the degree of pressure applied in the course of this compressing operation may .be varied according to the nature of the ing gredients of which the cakes are composed kand the special purpose for which they are intended, though the pressure exercised in Ithe feeding or longitudinal direction reirnains uniform, and this result is preferably `obtained by so constructing the mouthpiece 4or channel through which the ingredients are pressed that it is either reduced or enlarged Qin wid th by more or less rapid degrees in the lcourse of the operation-say by providing it with a flexible Wall for the purpose.

On the annexed sheet of drawings, Figure chine or press for carrying out this invention.

Figa 2 is avertical section of the mouthpiece ,of the press proper, the` said section being "taken on line y of Fig. l.

Figs. 3, 4, and 5 represent in sections taken at right angles to the section shown in Fig. 2 dierent forms of the mouthpiece which are obtained by means of ayielding adjustable plate or upper Wallof said piece. Fig. 6 is an elevation, partly in section, of` a modification of the press proper with a device for the preparaf tory compression which I consider is better regulated and more eectivethan that shown inFig.1` 'A' As illustrated by Fig. 1, the mixture to be compressed, consisting, essentially, of fibrous substances and of ground ordividedcereals,

ssl

as above indicated, is introduced byany suitable or well-known means into a suitable channelorehamber Ain whichheatiscaused i to act f uponi-the ingredients.4V 'Thiszheat'l mayy loe'` applied bya steam-jacket b, for example.

The .preparatory com pression effec ted by the plunger D, which is calculated eectually to promote the main compressing or molding process, may itself be further assisted, if desired, by the feeding or charging device B' in the casing B, the said casing communicating at its larger end with the feeding-channel A and at its smaller end with the casing containing the stamp or plunger D, so that a moderate forcing action is obtained by pressure against push-rod S, whichis raised by the pin F of an l eccentric or cam H and soon after passing the upper dead-point is released by a peg or toe n striking against the hub of the cam H and then freely descends toward the lower Vdeadpoint 2, at which it remains stationary until after the pin F on the cam H is once more thrown into gear with the recess provided near the lower end of the rod S, which rod S is pivoted to a working beam G, the fulcrum of which is at G'; A connecting-rod E connects the said beam G to the plunger D, this latter therefore partaking of the step-.by-step motion imparted to the push-rod S-that is to say, the plunger D after being raised falls freely from its uppermost position (shown in dotted lines) into its lowest position. (Shown in full lines). The stamp or plunger `D re` mains in the said lowest positionuntil the plunger fon moving forward has passed the point 2. This being done, the stamp or plu nger D is by the pin F, turning through the points 3a 4a, moved upward so far that While the main piston freciprocates from the point 2 to the point 3 and back to the point 4 the orifice of the conical casing B is being opened for the entrance of the mixture conveyed by the screw B'. The pin F of the cam passes the point 4E, and by its further rotation the said pin F carries the rod S with it until the peg n thereof has advanced toward the shaft` fw or the hub of the cam H, fixed on this shaft. The rod S being thus arrested, the pin F, rotating with the cam H in the direction toward the point la, leaves the recess of said rod S, y

and the latter bymeans of a roll fron the rod S rests upon the periphery of the cam H, and

for the time the concentric part of the cam is turning under rollr. The cam having passed the roll r loses its support and the plunger l D falls freely. Soon after this the pin F occupieslhe position la, which corresponds to point l of the plunger f,vand the latter pro-` pels the cake preparatorilv compresseduby the plunger D toward the orifice of the main press. On the plungerfarri ving at the-point 2 the pin F has reached the position .2, and here enters again the recess of the rod S and effects a fresh stroke of the plunger D. A pulley VM, mounted on the shaft w, im parts` motion to the pulley N and bevel-wheels O O, and sotransmits motion to the axis of thc conveying-screw B.

Providing means for preparatory compreslsion, as hereinabove described, enables the Vmain press or mold proper to be supplied `with cakes. Ythat have been already roughly pressed into shape, so that no portion of the material tobe molded into cakes is left a i chance of escaping sidewiseduring the whole of this gradual compressing process, the auxiliary or preliminary plunger closing the inlet-orifice until every particle of the material required to form a cake has been safely brought Within the stationary walls of the pressure-chamber.

Having fully described my invention, what I desire to claim and secure by Letters Patent of the United States isl. In a machine for themanufacture of cakes of food for cattle or the like, the combination of a preliminary pressing device, a feeding-channel communicating with said preliminary pressing device and iitted with a steam-jacket, a main pressure-chamber having an adjustable cover-plate, and a reciprocating plunger for compressing the material in said main pressure-chamber, substantially as described.
